The sum of two numbers is zero.
x + y = 0
y = -x
<span>Twice the smaller number subtracted from 3 times the larger number is 10.
Let x represent the larger number and y represent the smaller number.
Twice the smaller number: 2y
3 times the larger number: 3x
</span>Twice the smaller number subtracted from 3 times the larger number is 10.
3x - 2y = 10
-2y = -3x + 10
y = 3/2 x - 5
The equations are:
y = -x
y = 3/2 x - 5
The answer is the first choice.
To solve this problem you must appply the formula for simple interest, which is:
I = RxPxN
I: Simple Interest.
R:Rate (9.5$/100=0.095/12).
P: The principal (P=$9000).
N:number of periods (N=24).
When you substitute these values into the formula, you obtain:
I=RxPxN
I=(0.095/12)x9000x24
I=$1710
Therefore, the monthly payment is:
$1710/24=$71.25
What is Jerry's monthly payment?
The answer is: Jerry's monthly payment is $71.25
Part 1:
From the table, in week 1, the price increased by $1.25, in week 2, the price decreased by $3.125, in week 3, the price increased by $0.625 and in week 4, the price increased by $1.5
After the 4 week the change in price is given by 1.25 - 3.125 + 0.625 + 1.5 = 0.25.
Therefore, the price changed over the 4 weeks period by $0.25.
Part 2:
After the 4 week the change in price is given by 1.25 - 3.125 + 0.625 + 1.5 = 0.25.
Therefore, the price increased over the 4 weeks period.
Part 3:
Given that the price of 1 gram of gold was $39.28 at the end of week 4. since the price of 1 gram of gold increased by $0.25 over the 4 weeks period, the price of 1 gram of gold at the beginning of week 1 is given by:
39.28 - 0.25 = $39.03
For the answer to the question above,
since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.
<span>That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value we multiply by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked. </span>
<span>You can also check this by plugging in values: </span>
<span>Assume 10 doors are knocked: </span>
<span>E(10) = 20(10)-50 = 200-50 = 150 </span>
<span>Assume 11 doors (1 more door) is knocked: </span>
<span>E(11) = 20(11)-50 = 220-50 = 170 </span>
<span>The increase from 1 door is $20.</span>
Answer:
0.5 A
Step-by-step explanation:
Hi,
I believe the question is incomplete. However, as per the information provided:
The simplest way to calculate the Current (unit is Amperage), is understanding the relationship between the three: Power, Voltage and Current.
<em>(Quick Tip: </em><em>W=AV</em><em>; where W -> Watts (Power), A -> Ampere (Current), V -> Volts (Voltage))</em>
Using the formula we calculate the Ampere:
W = A x V
60 = A x 120
60/120 = A (We divide the equation be 120)
0.5 = A (Simply reduce the fraction 60/120 = 1/2 = 0.5)
